China PN16 DN600 Double Shaft Wafer Butterfly Valve Factory, Exporter
Product Description
✓ Double Stem Design
In a double stem butterfly valve, the setup includes two shafts attached to each side of the disc, providing balanced support and reducing torsion on the disc during operation. The disc is supported by two stems rather than a single central stem. This design can provide better disc stability and reduce the potential for disc wobble.
✓ GGG50 Material
The body and disc are made from GGG50 ductile iron. GGG50 is a material designation for ductile iron, which has excellent tensile strength, durability, and resistance to impact and fatigue.
✓ Wafer Butterfly Valve
Suitable for installations where space is limited, especially in wafer or lugged configurations.
